Imaging Findings

Fig. 112.1 (A) Sagittal and (B) Coronal T1WI demonstrated a large mass involving the right parasellar region, exhibiting T1WI hypointense signal. Fig. 112.2 (A) Axial T2WI demonstrated marked hyperintensity. (B) T2* sequence demonstrated multiple prominent flow voids. The mass dislocates the right internal carotid artery medially and anteriorly. Fig. 112.3 (A–C) Coronal dynamic contrast-enhanced images demonstrated progressive filling-in enhancement. Fig. 112.4 (A) Coronal and (B) Axial delayed T1WI (obtained after Figs. 112.1–112.3) demonstrated greater enhancement. Fig. 112.5 Sagittal further delayed T1-weighted image (obtained after Figs. 112.1–112.4) revealed nearly homogeneous enhancement.
